Measurement and Testing


Jul 12 2009

Ametek Calibration Instruments (USA) announces that the Jofra® range of Industrial Pressure Indicators (IPI) is now ATEX and CSA certified for use in potentially explosive environments in the field or in calibration laboratories. ATEX is the primary intrinsically safe standard in the European Union while CSA refers to relevant Canadian and USA standards.

Accurate to ± 0.05% FS, the Jofra IPI can be used as a calibration reference or in applications where high accuracy pressure measurement is required from safety valve checks to system pressure verification. This new certification will allow the IPI to be used in any industry where there is a risk of flammable gases. These include oil refineries, off-shore platforms, chemical plants, gas production plants, oil and gas shipping, pharmaceuticals and in whisky distilleries.

Intrinsically safe Jofra IPI indicators are available in 10 different pressure ranges. They combine the simplicity of an analog gauge with the accuracy and easy-to-read display of a digital calibrator to give versatile and easy-to-use units with a fast and straightforward setup, intuitive functions, application flexibility and a long battery life.

 An RS232 interface is supplied as standard which can be used for configuration, calibration and to transfer measurement data from the gauge. It enables the Jofra IPI to be used as a pressure reference with Jofracal software, which in turn provides control of a complete calibration procedure, storage of results and a calibration audit trail through hard-copy certificates.

Many user configurable functions have been designed into the IPI including sampling rate, TARE, damping, auto shut off, and min-max. Once the gauge is configured, settings can be locked and password protected to prevent unauthorized changes to configuration.
